> This PR adds a new compiler warning for `@SuppressWarnings` annotations that > don't actually suppress any warnings. > > Summary of code changes: > > * Add new warning and associated lint category `"suppression"` > * Update `LintMapper` to keep track of which `@SuppressWarnings` suppressions > have been validated ¹ > * Update `Log.warning()` so it validates any current suppression of the > warning's lint category in effect. > * Add a new `validate` parameter to `Lint.isEnabled()` and > `Lint.isSuppressed()` that specifies whether to also validate any current > suppression. > * Add `Lint.isActive()` to check whether a category is enabled _or_ > suppression of the category is being tracked - in other words, whether the > warning calculation needs to be performed. Used for non-trivial warning > calculations. > * Add `-Xlint:-suppression` flags to `*.gmk` build files so the build doesn't > break > > ¹ The suppression of a lint category is "validated" as soon as it suppresses > some warning in that category
